Water tank foam combined with fire truck dual agent fire fighting and rescue large capacity storage tank effectively put out Class A and Class B fires

Description :

  Water tank foam combined fire truck is a special fire vehicle integrating water tank and foam tank, which is mainly used to put out Class A solid fire and Class B liquid fire. The vehicle carries water or foam mixture to the fire site through on-board fire pump to realize rapid fire fighting and rescue. Typical working conditions include emergency response in petrochemical enterprises, oil depots, airports, ports, and general urban fire scenes. Its core advantage lies in having dual fire extinguishing media, which can be flexibly switched or used in combination according to the fire situation, effectively responding to complex fire scenarios, improving fire extinguishing efficiency, and reducing disaster losses.

  The specification parameters of the water tank foam combined fire truck are usually designed based on the chassis bearing capacity. The common water tank capacity is between 2 tons and 15 tons, and the foam tank capacity is between 0.5 tons and 3 tons. The body materials are mostly made of high-quality stainless steel or carbon steel for anti-corrosion treatment, ensuring corrosion resistance and service life. The execution standard complies with the GB 7956 "Fire Truck" series of national standards, equipped with high-performance fire pumps, with a rated flow rate usually ranging from 30L/s to 60L/s, and a working pressure of over 1.0MPa. The vehicle is also equipped with a foam proportioner to ensure that the foam mixing ratio is stable at 3% or 6% to meet the use requirements of various foam extinguishing agents.

  When selecting the type of water tank foam combined fire truck, the tank capacity shall be determined according to the fire type and scale of the protected object. For large petrochemical bases, it is recommended to choose high-capacity and high flow vehicle models; For ordinary urban fire stations, medium-sized vehicles are more flexible. Please note that this vehicle model is not suitable for extinguishing fires caused by live equipment or chemical fires that react violently with water. Dry powder or carbon dioxide fire trucks should be used in such scenarios. Compared with the pure water tank fire truck, the combined vehicle adds a foam system, which is slightly higher in cost but more widely applicable; Compared with specialized fire trucks, their main focus is on firefighting rather than rescue assistance, and the main combat tasks need to be clearly defined when purchasing.

  The daily maintenance of water tank foam combined fire truck is very important. Thoroughly clean the tank and pipeline after each use to prevent foam residues from corroding metal parts. Regularly inspect the sealing and lubrication of the fire pump to ensure rapid start-up and smooth operation. The foam proportioner shall be calibrated regularly to ensure the mixing accuracy. During winter use, it is necessary to drain the accumulated water in the pump and pipeline to prevent freezing and cracking. Common failures include that the foam does not produce liquid or the mixing ratio is not correct, which is often caused by the blockage of the pipette or the failure of the proportioner, so it is necessary to clean or replace the parts in time. It is recommended to conduct a full system test launch every six months to ensure good combat readiness.
